sbt-assembly: How do I exclude the configuration files in src/main/resources

问题

I am using sbtassembly from https://github.com/sbt/sbt-assembly to package my project.

I'm wondering is there anyway to exclude the resource files?

回答1:

You can specify files (and paths) to exclude by customizing the mergeStrategy: https://github.com/sbt/sbt-assembly#excluding-specific-files

So for discarding specific file you can do something like this:

// build.sbt

assemblyMergeStrategy in assembly := {
  case PathList("about.html") => MergeStrategy.discard
  case x =>
    val oldStrategy = (assemblyMergeStrategy in assembly).value
    oldStrategy(x)
}

Here's the documentaion for all available strategies: https://github.com/sbt/sbt-assembly#merge-strategy

Using Dani's approach with sbt 0.13.13, the config files were still included in my jar. This worked, though:

excludeFilter in Compile := "myconfig.conf",

In my case, all the files have the same name, myconfig.conf, but exist within a tree structure under src/main/resources/config. I tried:

unmanagedResourceDirectories in Compile += { baseDirectory.value / "src/main/resources/config" },

But it removed the directories from the jar, leaving the files.

It's documented here: http://www.scala-sbt.org/0.13/docs/Howto-Customizing-Paths.html
